Prognostic Significance of Subclassification of Extracapsular Extension in Prostate Cancer: Study of 673 Patients at a Large Academic Institution

The finding of extracapsular extension (ECE) of prostate cancer (PRCA) in a radical prostatectomy (RP) specimen is a poor prognostic factor. ECE has been divided into “focal” (F) (ECE tumor dimension u003c0.8 mm) and “established” (E) (≥0.8 mm). We investigated the utility of a third category, “multifocal” (MF), comprising more than one focus of ECE (u003c0.8 mm), …
